My invention relates to a'massage deyice. An important object of the mventlon is to provide a device of the above-mentloned character, which is of simplified construction, in-

expensive to manufacture, and is highly convenient in use. 7

In the accompanying drawing forming a part of this specification, and in whichflike numerals are employed to designate like parts 10 throughout the same, Figure 1 is a side elevation (of a device em:

bodying my invention, parts being shown in central vertical section,

vice, parts omitted. r t

Figure 3 is a perspective view of a tubular shaft and associated elements, parts omitted. In the drawing, wherein for the purpose of illustration is shown a preferred embodinates the casing of a motor, of any well known and preferred construction. This motor includes an armature shaft, 6, carrying the this armature shaft is journaled in a bearing 7 The motor casing 5 is rigidly mounted upon a handle 8, and has its longitudinal axis disposed at a right angle to the longitudinal axis of the handle. The handle is preferably tubular for receiving the lead wires 9, extending to the motor,'whereby current may be supplied thereto to drive the same, as is customary.

The motor casing 5 is circular'in cross-secternally screw-threaded forreceiving an externally screw-threaded extension 10, of a coupling ring 11. This coupling ring is included in a spider comprising radial arms or spokes 12, rigidly secured thereto, and rigidly secured to a hub or bearing 13, which receives the forward portion of the armature shaft 6, as shown. The outer couplingring '14, surrounds the inner coupling ring 10, in spaced concentric relation, and isrigidly attached "th'ereto by spaced radial elements or webs 15,

affording passages 16. These passages are arranged to discharge air rearwardly over the motor casmg 5, thereby servmg to cool 7 the same. 1

The rear end of tion, and its forward side is open and is in- The numeral 17 designates a shield, which is circular in cross-section, and tapers forwardly. This shield-embodies a rear shield section 18, tapering forwardly,-and having its rear-large end mounted upon the outer 5 [coupling ring 14:,and h avingscrew-thr eaded arranged interiorly of the forward end 'ofjthe shield section 19"and having screw-threaded 7 engagement therewith. 1

The numeral 23' designates a rotaryidisc, constituting the body portion ofa fan element, This rotary dischas a rearwardly projecting annular flange 2 1, operating: in7 cross relationto the inner coupling ring 11, and preferably slidably contacting there with. This rotary disc closes the inner side of a passage 25, the outer side of which is defined by the shield 18. Preferably formed integral with the forward'side of the rotary disc 23 are longitudinally curved generally radial vanes 26, spaced as shown, for provid- I ing air passages 27. The disc 23 is formed integral with a tubular hub 28, which is clampedto the armature shaft 6, by a set screw 29, or'the like. Thehub 28 is provided with a sleeve 30, as shown.

The numeral 31 designates a tubular shaft,

l which is slidably mounted upon the forward I end of thearmature shaft 6, and has 'longi-- tudinal slots 32, receiving a transverse "pin 33, which limits the relative longitudinal 'movement ofqthe tubular shaft. Disposed I .at theforward end of the tubular shaft is a massage element 34, formed of rubber, or the like, having a desired degree of stifiness and resiliency. This massage element is suitably attached to a cup shaped back 35,

which may have screw-threaded engagem t with the forward end of the tubular shaft 31, and 1S clamped to this shaft by a ring nut 36, having screw-threaded engagement 7 with the tubular shaft. This ring nut is engaged by a compressible coil spring 37,

which surrounds the tubular shaft 31 in spaced relation. "-The rearend of the spring 37 is arranged upon the stationary sleeve 30, and engages within a recess formed in ring 38, which is suitably clamped to the sleeve 30. r
